Towards Fast, Flexible and Sensor-Free Control of Standalone PVDG Systems
摘要：
本论文主要研究独立光伏分布式发电系统的快速、有效、低成本控制问题。当电力通过直流传输时，由于消除了传输损耗和不必要的能量转换，这些系统的现场发电效率更高。这些系统固有的低惯性，加上输出功率的波动和不确定的负载消耗，需要先进的控制技术，以确保在各种故障期间快速和稳定的运行。这些技术是昂贵的，因为它们需要安装许多复杂的传感器。快速发展的IC技术提供的计算能力可用于估计系统中的不同参数，并减少对昂贵传感设备的需求。这项工作提供了解决方案中遇到的问题，更快，更稳定和无传感器的电压控制和最大功率点跟踪（MPPT）的SPVDG系统与光伏和电池的发展。
英文摘要：
In this thesis, the problem of fast, effective and low cost control of a Standalone Photovoltaic Distributed Generation (SPVDG) system is considered . On-site generation from these systems is more efficient when the power is transmitted via DC due to elimination of transmission losses and needless energy conversions. The inherent low-inertia of these systems added with fluctuation of output power and uncertain load consumption, calls for advanced control techniques to ensure fast and stable operation during various intermittencies. These techniques are expensive since they demand installation of many sophisticated sensors. The computation power provided by the fast growing IC technology can be utilized to estimate different parameters in a system and reduce the need for expensive sensing equipment. This work provides solutions to problems encountered in the development of faster, more stable and sensor-free voltage control and maximum power point tracking(MPPT) for SPVDG systems with PV and battery.
